That *seemed* to do it, though I had CFLAGS= -O6, not O3, if I'm even looking
in the right place. It built some executables, and only gave warnings, no
errors, for example:

jdsample.c:308: warning: integer constant is too large for "long" type
jdsample.c:308: warning: integer constant is too large for "long" type
jdsample.c:309: warning: integer constant is too large for "long" type
jdsample.c:309: warning: integer constant is too large for "long" type
jdsample.c:310: warning: integer constant is too large for "long" type
jdsample.c:310: warning: integer constant is too large for "long" type
jdsample.c:311: warning: integer constant is too large for "long" type
jdsample.c:311: warning: integer constant is too large for "long" type
jdsample.c:312: warning: integer constant is too large for "long" type

...anyhow, am I heading down the right path? I'm assuming that building
mjpegtools from source *with* the nasm package installed will speed up the
conversion process from DivX to SVCD?

Thanks very much!
